Add Unit Tests for Chip Control

Summary

This PR adds comprehensive unit tests for the Chip control, which previously had no test coverage.

Changes

• ✅ Added ChipTests.cs with 14 unit tests covering all functionality of the Chip control
• ✅ Tests follow the existing testing patterns used in the repository (TUnit framework)
• ✅ All tests use STAThreadExecutor for WPF compatibility

Test Structure

Each test follows the pattern:

1. Create a Chip instance
2. Assert default values
3. Set property values
4. Assert the values are correctly set/retrieved

Event and command tests:

1. Create a Chip instance and apply default style
2. Set up event handlers or commands
3. Simulate user interaction (button click)
4. Assert expected behavior occurred

hi @Keboo
can you please check this pull request?

Thank you for the contribution. However, for most of the controls we do the testing through the UI test framework XAMLTest. The test project is MaterialDesignThemes.UITests. Testing at that level ensure that the WPF templates and styles also are tested rather than testing the control classes directly.
